ASYM/SYM VDSL Configuration Switch
The ASYM/SYM (Right Center) switch selects the maximum data rate for
the VDSL line. The ASYM (asymmetrical) position is the factory default
position, which allows the Subscriber a maximum receive data rate of 100
Mbps and a maximum transmit data rate of 60 Mbps. The SYM
(symmetrical) position limits the receive and transmit line rates in a
symmetrical manner so the line rates in both directions are approximately
the same.
6 dB/9 dB VDSL Configuration Switch
The 6 dB/9 dB (Right) switch selects the optimum signal to noise ratio
(SNR) for your VDSL line which is dependent on the line length of the
coaxial cable. The factory default setting for this switch is 6 dB SNR and
assumes that your VDSL line is less than 305 meters (1000 feet) in length.
Select the 9 dB SNR setting if your VDSL line is between 305 meters and
3000 meters (9842 feet) or if a more stable link and more noise protection
is needed.
